I bought some tickets on ryanair throught someone card like 4-5 trips to tenerife and then I decided to buy with my cash! Everything was good until I reached gateway and they said my ticket is invalid, called ryanair and they said under my passport number is outstanding amount of 1500 euros xD Which I had to pay to unlock my freshly ticket bought with my cash!
